Address configuration for target devices
Table C.4 lists related topics the administrator must understand when planning and implementing
the private IP addresses and provides links to where they are documented.
Table C.4: Tasks for Creating Addresses to Assign to Target Devices
Task Where Described
Private IP addresses must be defined by the creation
of at least one private subnet.
A private subnet must be created for each IP address
range used by the target devices.
• Why define private subnets? on page 182
• Configuring a private subnet on page 183
• Example 1: Private subnet configuration on
page 184
• Example 2: Two private subnets and VPN
configuration on page 185
Private subnet(s) should use IP addresses from one
of the three IP address ranges reserved for use on
internal networks.
• Using reserved IP addresses for private IP
addressing on page 181
Even if virtual IP addresses are used (as described
below), the planned real IP address for each target
device must be either configured manually as a static
IP address or configured as a fixed address in the
DHCP server dhcp.conf configuration file.
• Options for assigning IP addresses to target
devices on page 198
A virtual network may be created in the
following cases:
• To hide a target device’s private IP addresses
from non-administrative users who are not
configured for native IP access.
• When it is desired that multiple non-contiguous
private subnets be supported by a single network
route (or, in the case of IPSec, a single tunnel)
on the client for VPN or native IP access. This
would be the case when target devices are
already configured using IP addresses from
multiple address ranges and it is not feasible to
change previously defined target device
IP addresses.
• Why define virtual (DNAT) addresses? on
page 192
• To Configure IP Addresses From Multiple
Ranges
• Example 3: Virtual network with two private
subnets and VPN configuration on page 193
